United States Patent 3,202,685 3,3'-STEROID AZINES Andrew John Manson, North Greenbush, N.Y., assignor to Sterling Drug Inc., New York, N.Y., a corporation of Delaware No Drawing. Filed Aug. 30, 1963, Ser. No. 305,867 2 Claims. (Cl. 260-3975) N N:C: n

C no (I) a CH;

wherein R stands for hydrogen or a lower-carboxylic acyl group, and R stands for a lower-alkyl group.

When R in the above formula stands for a lower-carboXylic acyl group, it represents an acyl group derived from a carboxylic acid having from one to about ten carbon atoms and a molecular weight less than about 200. Representative of the acyl radicals which are contemplated are lower-alkanoyl radicals, e.g., formyl, acetyl, propionyl, butyryl, isobutyryl, caproyl, heptanoyl, octanoyl, trimethylacetyl, and the like; carboxy-lower-alkanoyl radicals, e.g., 'succinyl (fi-carboxypropionyl); cycloalkyl-lower-alkanoyl radicals, e.g., succinyl (,B-carboxypropionyl); cycloalkyl-lower-alkanoyl radicals, e.g., B- cyclopentylpropionyl, ,8 cyclohexylpropionyl, and the like; monocarbocyclic aroyl radicals, e.g., benzoyl, p toluyl, p nitrobenzoyl, 3,4,5 trirnethoxybenzoyl, and the like; monocarbocyclic aryl-lower-alkanoyl or -alkenoyl radicals, such as phenylacetyl, fa -phenylpropionyl, cinnamoyl, and the like; and monocarbocyclic aryloxy-lower-alkanoyl radicals, such as p-chlorophenoxyacetyl, and the like.

When R in the above formula stands for lower-alkyl, it represents an alkyl group having from one to about four carbon atoms, thus including methyl, ethyl, propyl, isopropyl, butyl, and the like.

The compounds of formula I are prepared by treating a steroid of the following general formula II with hydrazine.

R! CH3 5 lent of hydrazine in an inert solvent such as a lower- 70 alkanol.

The structures of the compounds of the invention were 7 material, M.P. about 282 C. (uncorn).

3,202,685 Patented Aug. 24, 1965 established by the mode of synthesis, by elementary anal- 'ysis and by ultraviolet and infrared spectra.

Endocrinological evaluation of the" compounds of the invention has shown that they are useful as endocrinological agents because they possess androgenic and anabolic activities.

The following will further illustrate the invention without the latter being limited thereby.

17a-methylandr0stan-1 7fl-ol-3-0ne azine Hydrazine hydrate (1.26 g.) was added to a solution of 7.00 g. of 17a-methylandrostan-17,8-01-3-one in ml. of methanol. The solution was warmed and concentrated on a steam bath until crystals appeared. The mixture was cooled and the prduct collected by filtration to give 1.94 g., M.P. about 286 C. (uncorr.). Concentration of the mother liquors afforded an additional 4.38 g. of The combined product was dissolved in 800 ml. of methanol and 100 ml. of chloroform, and the solution was concentrated until crystallization began. The recrystallized material Was dissolved in 200 ml. of chloroform, the solution concentrated to a volumeof 40 ml., and 40 ml. of methanol was added. The material which separated Was collected by filtration and dried for twenty hours at 100 C. to give 17a-methylandrostan-17 3-01-3-one azine, MLD. 287.8- 290.8 C. (corn); [a] =+17.90 (1% in chloroform); ultraviolet shoulder at 232 m (e=2600); infrared absorption at 2.88, 2.79, 3.45, 6.11, 6.80, 6.90 and 7.00,u.

By replacing the 17ot-methylandrostan-17 9-ol-3-one in the foregoing preparation by a molar equivalent amount of 17B-acetoxy-17a-methylandrostan-3-one, 17,8-propion- OXy)-c methylandrostan 3 one, (18 7 carboxypropionoxy) 17a methylandrostan-B-one, 17/3-(B-cyclopentylpropionoxy) 17a-methylandrostan-3-one, l7B-benzoyloxy-17u-methylandrostan-3-one, 17B-caproyloXy-17amethylandrostan 3 one, 17B-(p-nitrobenzoyloxy)-17amethylandrostan-3-one, or l7/3-cinnamoyloxy-17a-methylandrostan-3-one,'there can be obtained, respectively the 17- acetate, 17-propionate, l7-hemisuccinate, l7-fi-cyclo {jolt in 11. wherein R is a member of the group consisting of hydrogen and loWer-carboxylic acyl, and R is lower-alkyl.

2. 17a-methylandrost-an-17/3-ol-3-one azine.
